The following specifically explains the embodiment of the present application as applied to solving the problem of avoiding interference between WiFi device transmission and ZigBee device reception of the same gateway device or an adjacent gateway device.
In the embodiment of the application, the same gateway device integrates a WiFi device 0 (logic device) and a ZigBee device 0 (logic device), or a WiFi device 0 (logic device) and a ZigBee device 0 (logic device) in adjacent gateway devices, the WiFi device 0 and the ZigBee device 0 serve as master devices, and the WiFi device 0 connects a WiFi device 1 and a WiFi device 2 serving as slave devices through a WiFi network; the ZigBee device 0 is connected to the ZigBee device 1 and the ZigBee device 2 as slave devices through a ZigBee network.
As shown in fig. 5, in the embodiment of the present application, the WiFi device 0 has a CSMA/CA mechanism capability on the ZigBee channel in addition to the WiFi channel (for example, if the WiFi of the WiFi device 0 operates on 6 channels, the bandwidth is 20Mzh, then CSMA/CA detection should be performed on the ZigBee channels 15, 16, 17, and 18). When the ZigBee device 1 prepares to send a ZigBee message to the ZigBee device 0, firstly, an RTS message is sent to the ZigBee device 0 according to a CSMA/CA mechanism, the ZigBee device 0 returns a CTS message to the ZigBee device 1 according to the received RTS message and the CSMA/CA mechanism, the ZigBee device 1 sends the ZigBee message to the ZigBee device 0 according to the received CTS message, the ZigBee device 2 backs off according to the CSMA/CA mechanism, at the moment, the WiFi device 0 can detect the RTS message sent by the ZigBee device 1 and the CTS message responded by the ZigBee device 0, and the WiFi device 0 can calculate the time of the back-off according to the RTS message and the CTS.
In this embodiment of the application, it may also be determined, according to the signal strength of the ZigBee device 0, whether WiFi transmission of the WiFi device 0 would generate severe interference on ZigBee reception of the ZigBee device 0 (when it is detected that the signal strength of the ZigBee device 0 is greater than a signal strength threshold, it is usually determined that the ZigBee device 0 and the WiFi device 0 are in the same gateway device or in a neighboring gateway device), and if severe interference would be generated on ZigBee reception, backoff (the WiFi device 0 does not transmit a message) is performed for a preset time. After the ZigBee device 0 finishes receiving the ZigBee data, the WiFi device 0 sends a WiFi message according to a CSMA/CA mechanism of a WiFi channel, so that the ZigBee message of the ZigBee device 0 is received, and the problem of network interference between the ZigBee device 0 and the WiFi device 0 is solved.
As shown in fig. 6, a Radio Frequency (RF) 2.4Ghz Radio signal is received through an antenna, IQ quadrature demodulation (two mutually orthogonal carriers) is performed on the Radio signal to obtain a demodulated signal, an I signal and a Q signal are calculated according to an RF carrier (center Frequency), and then ZigBee demodulation processing and WiFi demodulation processing are performed on the I signal and the Q signal, respectively. For the WiFi signal of 2.4Ghz, the WiFi message can be obtained after the WiFi demodulation processing, and for the ZigBee signal of 2.4Ghz, the ZigBee message can be obtained after the ZigBee demodulation processing.
In the embodiment of the application, since WiFi and ZigBee networks in the same gateway device or adjacent gateway devices may interfere with all channels of the 2.4Ghz band of ZigBee, the ZigBee demodulation processing should demodulate the I signal and the Q signal on all channels of the 2.4Ghz band of ZigBee. In order to reduce the calculation amount of the ZigBee demodulation process, the operating channel of the ZigBee device 0 may be determined in a configuration manner, or the channel where the neighboring ZigBee device is located may be determined by determining that the signal strength of the ZigBee device 0 is greater than a 2.4Ghz signal with a certain signal strength threshold. It should be noted that, the ZigBee device 0 is usually a single-channel transceiver, and only one of the channels needs to support ZigBee demodulation processing.

and S111, CSMA/CA detection is carried out in the overlapped WiFi channel and ZigBee channel through the WiFi device 0.
S112, judging whether a CTS message sent by the ZigBee device 0 on the ZigBee channel and a received RTS message are detected or not, if so, turning to the step S113; otherwise, go to step S115.
S113, according to the detected CTS message sent by the ZigBee device 0 in the ZigBee channel and the received RTS message, calculating the preset time length for the WiFi device 0 to stop sending the message in the WiFi channel.
S114, the ZigBee device 0 receives a ZigBee message sent from another ZigBee device (ZigBee device 1 or ZigBee device 2) as a slave device, and goes to step S115.
S115, the ZigBee device 0 receives the idle state, and the WiFi device 0 can send a WiFi message.
And S116, the WiFi device 0 sends the WiFi message according to the normal message sending process.
In another embodiment of the present application, the WiFi device 0 works normally after being powered on, and the WiFi device 1, the WiFi device 2 and the WiFi device 0 communicate; the ZigBee device 1, the ZigBee device 2, and the ZigBee device 0 communicate with each other, as shown in fig. 8, the network anti-interference method includes:
and S211, CSMA/CA detection is carried out in the overlapped WiFi channel and the ZigBee channel through the WiFi device 0.
S212, when the signal intensity of the ZigBee device 0 on the ZigBee channel is detected to be larger than the signal intensity threshold value, the ZigBee device 0 is added into the sending avoidance list.
S213, detecting whether the transmitted CTS message and the received RTS message exist in the ZigBee channel of the ZigBee device 0 in the transmitting and avoiding list, and if so, turning to the step S214; otherwise, go to step S216.
